Accounting for the mechanical interactions between the flow of a fluid and the deformations of a structure for coupled systems is crucial for better sizing certain parts or components (as in the renewable energy or naval sectors). “Co-simulation” techniques, aimed at taking advantage of the functionalities offered by numerical tools dedicated to the dynamics of fluids and structures and at coupling these tools, are one of the innovations proposed by computer code editors for allow engineers to simulate various fluid-structure interaction problems.
Fruit of academic research, which has proposed efficient coupling algorithms, with demonstrated numerical properties (accuracy, stability, etc.), and of industrial developments, which have accompanied the implementation of these algorithms in engineering tools, these “co-simulation” techniques, which are complex to use, are still little used by engineers.
We propose feedback on an R&D project aimed at evaluating, validating and disseminating these techniques in the naval industry. Conducted within the framework of a collaboration with academic partners, relying on test results and receiving the support of publishers of digital solutions, the project has made it possible to highlight the opportunities offered by these calculation and to identify the limits of use for applications to the hydrodynamics of deformable supporting profiles.
